I have found that 2 things retain water:
SALT, the biggest offender...look to your soy sauce.
SUGAR, a lesser offender that "carb loads" as glycogen with lots of water into the muscles and liver.
I was surprised to see the effect of the latter but for me it's real. The effect of the carbs is pronounced only when I have A LOT of quick carbs...like a big spaghetti dinner and a wedge of chocolate cake.
Of the two the "prettier" weight gain is the carby one, because my muscles are all pumped. With the saltwater gain, it's squish in all the wrong places...like fingers and eyelids!
(I too, have been banging away at 201-205# for the last year...something about that number
